Title: Improvements in or relating to cables, and machines and processes for their manufacture
Inventor: FUCHS GEORGES
IPC: H01B11/00
Filed: 1966-03-31
Abstract: 1,103,500. Cables. SOC ANON DE TELECOMMUNICATIONS. 31 March, 1966 [1 April, 1965], No. 14202/66. Heading H1A. A cable comprises at least two coaxial pairs of which the outer conductor of each pair is in the form of a metal strip formed into a tube with overlapping edges and is held in contact with the insulation surrounding its inner conductor by a twist imparted to it only during the stranding of a number of such coaxial pairs together. The outer conductors may consist of a copper and a steel strip formed into a composite or bi-metal strip. Three methods of producing such a cable are described. In the method illustrated, the rotary cage of a cablemaking machine has supply reels 32 loaded with insulated inner conductors 31 and additional reels 27 loaded with metal or metal composite strip 28. Also fixed to and rotating with the cage are dies 29 attached to plate 30 in which the metal strip is folded over the insulated inner conductor. A number of the so-formed coaxial pairs are then drawn through a stationary die and twisted together and the resulting cable may be lapped with tape. The composite strip outer conductor may also be formed on the insulation by loading the supply reels 32 with coaxial pairs having a copper strip outer conductor and loading reels 17 with steel strip. In addition to rotating the cradle, the gearing 37 may enable the supply reels 32 to rotate independently of the cradle thus giving a relative twist between elements 31 and 28. In an alternative method, coaxial pairs with metal strip outer conductors contained in the suppy reels of a rotary cage may be stranded directly together, Fig. 4 (not shown) In yet another method, Fig. 6 (not shown),. the supply reels contain insulated inner conductors and two additional sets of reels contain different metallic strips and these are folded in turn over the insulated inner conductor and the coaxial pairs thus formed stranded together in one operation. Cables formed by any of these methods may be stranded together to form composite larger cables.

Title: Incandescent safety lamps for mines
IPC: F23N1/00
Filed: 1922-02-22
Abstract: 198,686. Ferrette, L. E. F. Feb. 23, 1921, [Convention date]. Oil reservoirs.-The air pump in the reservoir of a miners' incandescent safety lamp is provided with means for preventing an excessive pressure in the reservoir. The pump illustrated comprises a piston 51 and a tubular piston-rod 46 reciprocable in a barrel 44 which is arranged in the lamp reservoir 1 and is surrounded by a protecting tube 63. On the inward stroke of the piston the operator places his thumb over the opening in the piston-rod and air is forced through a spring-pressed valve 49 in a valve seat 56 into a chamber in the barrel 44 between the seat 56 and a diaphragm 55, when the piston contacts with a tail-piece 60 on the valve 49. This chamber communicates with the reservoir through ports 54, 62 formed in the barrel 44 and tube 63 respectively. When the reservoir pressure exceeds a predetermined limit, the air escapes through a spring-pressed valve 58 into a chamber in the barrel 44 between the valve seat 57 and the diaphragm 55 and then escapes through a bye-pass 61 and the hollow piston-rod 46 into the atmosphere on the return stroke. In the innermost position of the piston the operating button 47 on the piston rod enters a recess in a disc member 50 closing the barrel body 44.

Patent GB-216695-A (GB)
Title: Improvements in the treatment of zinc-lead sulphide ores, mattes and the like
IPC: C22B13/02
Filed: 1923-06-02
Abstract: Ores, concentrates, &c. containing zinc are chlorinated by chlorine or sulphur chloride at 600-700 DEG  C. in known manner, preferably with the addition of carbon if much oxygen is present, any arsenic, antimony or tin present being expelled as chlorides, which may be condensed.  The iron and some or all of the lead and silver are precipitated from the melt by adding the requisite quantity of zinc, forming a non-fused granular alloy which after washing is smelted for the metals.  The sulphur and some zinc chloride liberated in the chlorination are received in a condenser, the sulphur condensing as a layer upon the surface of a strong solution of zinc chloride in the condenser, while the zinc chloride vapour condenses and dissolves in the solution.  From time to time zinc chloride solution is withdrawn from the condenser, mixed with fresh ore, and the mixture dried and fed to the chlorinating apparatus, and the solution in the condenser is made up with the wash water of the iron-lead alloy.  The purified zinc chloride or zinc and lead chloride is electrolyzed and the chlorine is employed again for treating fresh ore.  The electrolysis is preferably effected in the apparatus described in Specifications 198,024 and 208,649, [both in Class 39 (iii), Heating by electricity], and the products successively deposited are, when nearly all the lead has been deposited, first impure zinc containing lead, copper, &c. and then pure zinc, or, when the melt contains a substantial quantity of lead chloride, first an alloy of lead, silver, &c., then pure lead, then a lead-zinc alloy, and finally pure zinc.  The presence of some manganese during the electrolysis is advantageous and a manganese compound may be added if manganese is not present in sufficient quantity. In a modification, the chlorination is effected at a low temperature with sulphur chloride as described in Specification 200,701, and the product (containing sulphur and sulphur chloride) is introduced into fused zinc chloride at 400-450 DEG  C., the mixture being treated with zinc to precipitate the iron-lead alloy and the purified melt being then electrolyzed when chlorine and sulphurchloride are evolved; or the mixture of the chlorinated ore and zinc chloride may be heated to 600-700 DEG  C., for instance by feeding it into a previously obtained melt kept at that temperature when sulphur is distilled off leaving a chloride melt which is treated with zinc and subsequently electrolyzed as before.

Title: Improvements in towing ceramic ware
IPC: B28B11/18
Filed: 1964-04-08
Abstract: 1,042,267. Towing ceramic ware. JOHNSON BROS. (HANLEY) Ltd., and G. W. BIRD. April 8, 1965 [April 8, 1964], No. 14593/64. Heading B3D. A method of towing ceramic ware, such as saucers and plates, comprises moving an article to be towed relative to a towing head 14 and causing a moving towing surface on the head to contact the moving article, the towing surface being constituted by at least one longitudinally moving endless belt 15. In apparatus for carrying out the method, the article to be towed is placed on cushioning rings 10 on a lower support plate 11 of plaster which rests on a work-table 22 and is formed with a metal member 20 having a conical seating 18 located in a recess 21 in the work-table. A conical member 17 is disposed below the support plate and when raised lifts the plate 11 to press the article against a resilient pad 12 on a shaft 13, the movement of which raises a weight 26 from a stop 27, the weight causing the article to be frictionally engaged between the rings 10 and pad 11 so that rotation of the shaft 30 by a belt-drive 32 is imparted to the article. The work-table is provided with four support plates 11 and is indexable either manually or automatically through a Geneva device to present articles on the support plates to the towing station. Brackets 23 having sponge rubber faces 24 are spaced symmetrically about the plates to locate the articles centrally with the support plates. The towing head 14 is movable about a pivot 34 by a piston-andcylinder device 35 and is counter-balanced by a weight 36. The towing head is enclosed by a cover 54 which, when removed, permits access to the drive for the towing surface which consists of a woven felt belt 15. The belt is entrained about a pulley 40, Fig. 2 (not shown), driven by a motor and is pressed against that pulley by a spring-urged wheel 41 on a lever 42. The belt also passes over a pair of pulleys 47, 48 on tensioning levers 50, 51, a pair of pulleys 45, 46 and a pair of pulleys 52, 53, pulley 52 being of nylon and pulley 53 of hardened steel. The bearings for pulleys 45, 46, 52 and 53 are on the other side of the base-plate and the base-plate is grooved so that air can pass across the bearings to assist in preventing dust entering the bearings. During towing, the belt moves in the direction of the arrow A, and sideways thrust on the belt at the towing position, caused by rotation of the article, is prevented by an arm 64, Fig. 3 (not shown). A flexible exhaust 39 is connected to a vacuum source to remove dust generated during towing. In another embodiment, the towing head has two belts which are arranged side-by-side but run in different planes forming an oblique angle at the towing position.

A back-up roller 11 hinged at 12 to the frame 6 and provided with an operating lever 13, applies slight pressure to the film and the strip. Immediately downstream of the roller 10, the film is cut along the edge of the strip by a blade (23), Fig. 3 (not shown). A flexible roller 14, Fig. 2, having a conical skirt assists removal of the cut film end 15 and is mounted on the same shaft as a roller 16 resting on the film. This shaft is inclined slightly to the transverse direction of the film. To effect cooling, the roller 10 comprises a cylindrical part 19 of a heat insulating material, e.g. polytetrafluoroethylene, and a hollow core 20 made of heat conducting material and provided with perforations 21 which may be fed with a cooling gas through a conduit 22. The roller 10 is applied to the strip 1 with the part 19 on the outside edge of the strip and part of the core 20 overlying the inside edge of the strip. Along the core 20, the amount of heat removed from the weld increases as the distanec from the part 19 increases. In a modification (not shown), a reinforcing strip is welded to the middle of a film and the applicator roller has two cooling zones one each side of a central insulating zone.  The film may be polyethylene or the strip may comprise a polyester layer between two polyethylene layers.

Title: Improvements in apparatus for gathering, delivering and transferring materials
IPC: B65G65/28
Filed: 1919-06-11
Abstract: 150,105. Stuart, F. L. June 11, 1919. Conveying and elevating apparatus.-Apparatus for transferring material comprises means by which material may be taken from a main belt conveyer and delivered to storage or other carriers, or may be gathered and transferred to the main conveyer which carries it to its destination. A wheeled truck B driven by motors D runs on a track parallel to the main conveyer A, and has an inclined frame E which supports the looped part A<1> of the conveyer and a frame G which supports a turntable H. The part A' passes round a delivery pulley a<1>, pulley a<2>, driving-pulleys a<4>, a<5>, tension pulleys a<6>, a' and a pulley a<3>. One of the driving-pulleys is connected by gearing f to a motor F. The turntable H supports a frame I in which a cradle J is pivotally mounted. The cradle J can be swung by mechanism actuated by a motor L and has a boom conveyer M slidably mounted in it. The frame m of the boom conveyer is moved by mechanism actuated by a motor N. The material discharged from the main conveyer as it passes over the pulley a<1> passes through hoppers P, P<1> and over a shoot P<2> to the belt m<1> of the boom conveyer. The shoot P<2> is connected by pivots p<2> to the hopper P' and is supported by wires q. The hopper P<1> is connected by pivots p to a ring p<1> which rests on a flange at the mouth of the hopper P. When the boom conveyer receives material and delivers it to the main conveyer belt, the shoot P<2> and hopper P<1> are raised by the wires q to the position shown by dotted lines, Fig. 5, and the belt m<1> discharges as it passes round the driving-pulley n<2> into the hopper 0 which discharges on to the main conveyer belt through the hopper 0. The hopper 0 has branches o, Fig. 6, on opposite sides of the boom conveyer. The gathering-mechanism for transferring material from a storage pile to the boom conveyer comprises a double-ended plough R, a belt conveyer r', and a hopper r<3>. The frame r<2> of the conveyer r<1> is detachably connected to the boom so that it may be replaced by a gathering-device in which the plough enters endways into the material. The hopper r<3> is pivoted at r<4> so that it may be raised when the boom conveyer is discharging material. The gathering-mechanism may be connected pivotally to the boom conveyer so that it may be swung independently in an horizontal plane. The turntable H may be rotated by mechanism actuated by a motor K, but for heavy work the boom conveyer, &c. is swung by an endless-track tractor S which may also be used for moving the conveyer longitudinally in its cradle. The outer end of the boom may be lowered by a cable T actuated by a winch T<1>, and this tackle may be used also for moving the boom in one direction about its vertical axis. A hopper U is provided into which the boom conveyer can deliver in case it is desired to return the material to the main conveyer belt for delivery to another apparatus for discharging it where required. Specification 150,587 is referred to.
